Fix global warming save the world

I believe that america's role in the world should be focusing on global warming. We should be focusing on this issue way more because our country starts crumbling away. The article on the global warming solutions website told us “ 2000, we’ve experienced 14 of the 15 warmest years on record – including 2014, the hottest year ever recorded. As the oceans warm, we’re learning that it’s no longer a question of if the Antarctic ice sheet will melt but how fast.”  This is a serious issue in the world right now and needs to be settled. The United States is often noted as the being the most significant contributor to historical emissions of global warming pollution. Most of these emissions occur when power plants burn coal or natural gas and when vehicles burn gasoline or diesel. These are all controllable things that we can fix to change the future if we just focus on it.Solutions to global warming in North America include reducing coal emissions, increasing the use of energy efficiency and renewable energy, greening transportation, and helping developing countries reduce deforestation.
